 The   rubber dam bladder for good quality is made of strength canvas and rubber layer which ensure tightness of the rubber layers. The rubber layers encompass outer, middle and inner elements for different functions

Strength canvas

 

       The outer layer is made of the special rubber material characterized by wear, sunlight, heat and ozone-resistance.

         The middle layer is used for protection of canvas and for connection of 2 or more canvas with rubber layers

        The inner layer is used for protection of canvas and it is characterized by watertight and airtight features.

 

The outer, middle and inner rubber layers

 

      The cover rubber sheet is used to prevent the base board from leaking.  

Cover rubber sheet
